Our on-board and roadside equipment is complemented by our back-end systems. The system consists of a GPRS communication proxy, an expert system comprising Geo modeling as well as tariff modeling, the validation and pre-processing of toll data.

In addition, the back-end system handles the up-date of the OBU firm-ware, charging parameters and other OBU relevant configuration and complies with the highest security standards.

OBU and our proxy back end is called the "front end" according to RCI results and provides a perfect well definable interface towards the high level data processes.
